Researchers at the Oak Ridge National Laboratory have demonstrated a solid-state high-voltage (5 V) lithium battery with an extremely long cycle life (10,000 cycles) and high Coulombic efficiency (99.98%). The solid electrolyte enables the use of high-voltage cathodes and lithium anodes with minimal side reactions. The energy stored in a battery of a given size… Read more »

Sakti3 demonstrates impressive energy density with solid-state battery cells
For a few years, battery insiders have been talking about a startup company called Sakti3. The University of Michigan spin-out has received millions in funding from backers including Khosla Ventures and GM Ventures. Until recently, the company has been pretty secretive, but this week CEO Ann Marie Sastry told Scientific American that the company’s prototype… Read more »
Toyota researchers develop all-solid-state Li-ion batteries
As Toyota plans to bring a fuel cell vehicle to market in 2015, its researchers continue to work on next-generation battery technologies. In a presentation at the International Meeting on Lithium Batteries in Como, Italy, Dr. Hideki Iba from Toyota’s Battery Research Division and Dr. Chihiro Yada from Toyota Motor Europe’s Advanced Technology Group noted… Read more »
University of Colorado researchers to commercialize new solid-state battery
The University of Colorado Boulder (CU) has signed an agreement with Solid Power LLC, a spin-off company, to develop and commercialize a solid-state battery technology that has the potential to greatly improve EV range. Solid Power, founded by Se-Hee Lee and Conrad Stoldt, both associate professors of mechanical engineering, was recently awarded a $3.4 million… Read more »
New report: Solid-state batteries will rule by 2030, driven by consumer electronics
A report from technology advisory firm Lux Research predicts that new battery technologies will become strong competitors with existing lithium-ion technology by 2020, and that solid-state batteries will surpass Li-ion by 2030. However, consumer electronics, not electric vehicles, will be the market driving the advances. “While much of the motivation for next-generation batteries – whether… Read more »
Registration Closes Friday for Europe’s Leading Automotive Battery Event
As Europe’s electrification strategy entering a more complex and fast-evolving phase, the upcoming AABC Europe 2026 offers a pivotal moment for the automotive and energy storage sectors to come together. Taking place in historic Mainz, the event will bring together more than 1,000 battery technologists, OEMs, and supply chain leaders to explore the technologies and… Read more »
High-potential testing for EVs: why reed relays raise confidence in insulation and safety
Sponsored by Pickering Interfaces. EV platforms live at the intersection of high voltage, high power and strict safety requirements. From battery packs and traction inverters to DC fast chargers and cable harnesses, engineers must prove that insulation is sound during development and at end-of-line. That is the role of high-potential testing. In a withstand test… Read more »
Vishay’s new automotive MOSFET driver delivers 8 mm creepage in compact SMD-4 package
Vishay Intertechnology has launched the VODA1275, an automotive-grade photovoltaic MOSFET driver that delivers 8 mm creepage distance and CTI 600 mold compound in a compact SMD-4 package. The device targets high voltage automotive applications including pre-charge circuits, wall chargers, and battery management systems for EVs and HEVs. The VODA1275 delivers 20 V open circuit voltage,… Read more »
Kulicke & Soffa’s new ASTERION-TW welds copper terminals without heat for power modules
Kulicke & Soffa has introduced ASTERION-TW, an ultrasonic terminal welding system for next-generation power module manufacturing, adding another solid-state interconnect option to its ASTERION platform. The company says the system is designed for high-reliability applications in markets including transportation, renewable energy and data centers, where conventional mass-reflow processes can be limiting. ASTERION-TW uses ultrasonic welding… Read more »
BYD unveils 1,500 kW EV charging station to go with its 450-mile EV battery
Last week, Chinese EV-maker BYD introduced its Blade Battery 2.0, which it says will deliver a range of over 1,000 km (that’s according to China’s CLTC rating system—using the US EPA’s testing system, it probably amounts to a still-impressive 725 km, or 450 miles), and can be charged in just 10 minutes. Of course, charging… Read more »
